3 Claims. (Cl. 30-61) This invention relates to new and usefulimprovements in a safety razor.

It is an object of this invention to provide a razor that will maintainthe cutting blade thereof in yieldable relation with the holder, so thatupon encountering tough beards, or the like, the blade will recede intoblade holder and thus preventing pulling the beard, or cutting the faceof the user.

It is another object of the invention to provide a razor that willmaintain the cutting blade in yieldable position,

and that will provide means for adjusting the tension on the blade.

It is still another object of the invention to provide a razor that willmaintain the blade yieldable against pressure in one direction and rigidagainst pressure in the other direction in the same holder.

With the above and other objects in view, the invention has relation tocertain novel features of construction and operation more particularlyset out in the following specifications and illustrated in theaccompanying drawings, wherein:

Figure l is a side elevational view, in cross section, of one form ofthe invention.

Figure 2 is an end view of the view shown in Figure 1.

Figure 3 is an elevational view, in cross section, of another form ofthe invention.

Figure 4 is an end view taken from the view shown in Figure 3.

Figure 5 is an elevational view, in perspective, of another form of theinvention.

Figure 6 is an elevational end view, in cross section.

Referring now more particularly to the drawings, the numeral 1designates a holder having a strip of resilient material, such as spongerubber, secured to the upper portion thereof in any suitable manner,such as by an adhesive. A single edge razor blade will be received bythe holder 1, and its upper edge will bear against the strip 2, theblade 3 being maintained in position by the hinged cover member 4. Theconventional handle will be mounted on the holder, as 5. When a toughbeard, or the like, is encountered, the blade 3 will bear against thestrip 2, and will recede into the holder members 1, 4, out of cuttingrelation.

In the form shown in Figures 3 and 4, the holder 6 has an adjustingscrew 7 mounted in the top thereof, which bears against the plate 8. Asimilar plate 9 is mounted in the holder 6 beneath the plate 8, and isseparated therefrom by the coil springs 10. Suitable studs project from"ice the plates 8, 9, such as the studs 11, 11, and fit into suitablegrooves as 12, 13 formed in the holder 6, which maintain the plates 8, 9in horizontal alignment. In this form of the invention, the blade 3bears against the plate 9, and the pressure on the blade 3 may beadjusted by the screw 7.

In the form shown in Figure 5, the holder 13 is for a double edge blade,and has a rigid bar 15 on which the resilient bar 14, such as spongerubber, is mounted. The double edge blade 17 is provided with a wideopening 18 to fit over both the rigid bar 15 and the resilient bar 14.The holder member 13 is provided with a stud 20, having suitable threadsthereon, to be received by the internally threaded port 16 in the holdermember 13. The conventional handle 21 is mounted on the holder member19. When the user desires a resilient blade in this form of theinvention, the side having the strip 14 is used, and when a rigid bladeis desired, the opposite side is used.

When a blade becomes dull, and would otherwise cause a poor, andpossibly painful, shave, the blade will recede into the holder, and willnot out either the beard or the skin of the user, thus indicating to theuser that a new blade is required.

While the foregoing is considered preferred forms of the invention, itis by way of illustration only, the broad principle of the inventionbeing defined by the appended claims.

What I claim is:

1. In a razor, a blade holder adapted to receive a single edge blade, apair of parallel barsmounted in said holder, said bars being spacedapart by a plurality of yieldable means, means for varying the pressureon said yieldable means, and means for yieldably maintaining said barsin longitudinal alignment, and means for maintaining a single edge bladein said holder in abutting relation with one of said bars.

2. In a razor, a blade holder, transverse grooves in said holder, a pairof longitudinal bars mounted in said holder, means for maintaining saidbars in longitudinal alignment and means for maintaining said bars inyieldable spaced relation, a single edge razor blade in said holder, andmeans for maintaining said blade in yieldable contact with said bars.

3. In a razor, a blade holder adapted to receive a single edge blade, apair of parallel bars mounted in said holder, and said holder havingtransverse grooves therein, projections on said bars extending into saidgrooves maintaining said bars in longitudinal alignment, yieldable meansbetween said bars maintaining said bars in spaced relaton, a single edgerazor blade in said holder having its reinforced edge bearing againstone of said yieldable bars.
